Reporting annually is part of the City’s commitment to address climate change, and inform the development of its climate strategy and policy.

A full dashboard of the 2016 GHG emissions inventory is available on the C40 Cities website. C40 is a network of the world’s megacities committed to addressing climate change.

The City follows the Greenhouse Gas Protocol for community-scale GHG emission inventories.
